Drainage density is related to various features of landscape dissection such as valley density, channel head source area, relief, climate and vegetation (Moglen et al. 1998), soil and rock properties (Kelson and Wells 1989) and landscape evolution processes.
The combined use of remote sensing based land cover classification and landscape metrics has provided a positive step toward gaining a comprehensive understanding of the features of landscape structure.
However, the functional features of landscape units at different structure levels, based on which outcomes can be enriched and advice can be given for practical applications, have been overlooked.
The results not only confirm the effectiveness of GIS-based spatial analysis and modeling approach in studying the ecological impacts of human activities, but also reveal the salient features of landscape dynamics in the desakota regions.
Artificial structures, such as pier pilings, floating pontoons, breakwaters and seawalls are becoming common features of landscape in shallow coastal waters of urbanised areas, in some areas, replacing considerable portions of natural habitats.
Dd is related to various features of landscape dissection such as valley density, channel head source area, relief (Montgomery and Dietrich 1989), climate and vegetation (Moglen et al. 1998), soil and rock properties (Smith 1958; Kelson and Wells 1989) and landscape evolution processes.
